Sure, you can set sail at Lake Eola. But instead of renting one of the swan-shaped paddleboats, you might be better off walking the lake’s nearly milelong perimeter, taking in the serene beauty of the urban greenspace, which includes an amphitheater and a children’s playground. On Sundays from 9 a.m. to 2 p.m., check out a small farmers’ market on the south side, where vendors sell fresh-brewed coffee, fruits, vegetables and baked goods.
